According to the present invention, disclosing such a kind of system, described system includes the shrinking connecting-rod being attached to the wheel of vehicle。Described system also includes sensor, the little overlapping area head-on crash of described sensor detected vehicle。Described system farther includes controller, and described controller is attached to sensor and shrinking connecting-rod。Controller activates shrinking connecting-rod when receiving the instruction of little overlapping area head-on crash vehicle being detected of sensor。When by controller actuating, shrinking connecting-rod makes rotation of wheel。
With reference now to Figure 1A-Fig. 1 D, it is shown that all kinds of front vehicle collision。Figure 1A shows the head-on crash of 40% skew of usual vehicle 100。In this scenario, vehicle 100 is with about 40% impacted object 102 of the anterior width of vehicle 100。Figure 1B shows the full-frontal collision of vehicle 100。Being different from the scene shown in Figure 1A, in the scene shown in fig. ib, the 100% of the frontal width of vehicle 100 impacts barrier 108。In two kinds of scenes, vehicle 100 keeps being relatively unaffected in car door region 104。This is because most of modern vehicle are designed to compensate for the collision in basic front。In other words, one or two front portion structure track of vehicle 100 can absorb and distribution impulsive force respectively in the head-on crash of 40% skew or full-frontal collision。Therefore, the polycrystalline substance of vehicle 100 can be configured to reduce impulsive force and passes into the passenger accommodation (such as by provide front plication region) of vehicle 100。
In Fig. 1 C-Fig. 1 D, it is shown that relate to the little overlapping area head-on crash of vehicle 100。In this scenario, the marginal portion impacted object 112 of the only frontal width of vehicle 100。For the purpose of impact test, this width is generally 20%+/-1%。It should be understood, however, that the actual any percentage ratio being likely to the frontal width with vehicle that clashes into produces (such as any percentage ratio less than the 21% of the frontal width of 1% to the vehicle of the frontal width of vehicle)。Being different from the scene shown in Figure 1A-Figure 1B, the little overlapping area collision shown in Fig. 1 C-Fig. 1 D confirms the vehicle 100 significant car door deformation in car door region 104。This is because vehicle 100 impacted object 112 by this way makes object 112 miss the front rail of framework of vehicle 100。Therefore, the impulsive force produced in the process collided with object 112 passes into car door region 104 via wheel 110 and is likely to collide the passenger accommodation of vehicle 100。Especially, impulsive force passes into body hinge post and the threshold vehicle of vehicle 100 from wheel 110。In other words, wheel 110 can provide Path of Force Transfer in the process of little overlapping area head-on crash, and impulsive force is transferred to car door region 104 by described Path of Force Transfer。
Fig. 2 A-Fig. 2 B shows the steering 200 for vehicle according to each embodiment。As shown in Figure 2 A, front-wheel 100 can be attached to deflecting roller 202 via steering link 208, gear-box 206 and steering column 204。When deflecting roller 202 rotates, revolving force is transferred to gear-box 206 via steering column 204。In each embodiment, steering column 204 can be fixing axle or can include any amount of connecting shaft (such as first-class via Universal connector), thus allows for deflecting roller 202 and is located relative to any position of gear-box 206。
As shown in more detail Fig. 2 B, the revolving force of gear-box 206 low damage post 204 in the future changes into pulling force or thrust F, and described pulling force or thrust F are transferred to steering link 210。Such as, gear-box 212 can use rack-and-pinion mechanism or any other suitable mechanism so that the revolving force of low damage post 204 changes into power F in the future。In some embodiments, steering pump (not shown) can provide hydraulic pressure to gear-box 206, therefore strengthens the pulling force on steering link 208 or thrust F。Especially, the suspension 212 of wheel 110 could be attached to both connecting rod 210 and control arm 210。Especially, when power F applies to when hanging 212 via steering link 210, wheel 204 can rotate around axle bush 214, and described axle bush 214 couples suspension 212 and control arm 210。Therefore direction of rotation is the function (such as, pull suspension 212 to will result in wheel 204 and rotate in one direction, and promote suspension 212 to will result in wheel 204 and rotate in the opposite direction) in the direction of power F。As will be appreciated, shown steering 200 is exemplary only, and other can be used within the scope of the invention to turn to structure。
Fig. 3 A shows the exemplary enforement mechanism 302 that could be attached to steering link 210。In each embodiment, enforement mechanism 302 is operable to, thus providing driving force when activateding to steering link 208。Such as, enforement mechanism 302 can include pyrotechnics, hydraulic pressure or gas activated piston, and described piston drives steering link 208 to enter wheel 110, causes the rear end of wheel to be pivoted away from vehicle in the process of little overlapping area head-on crash。Especially, and as described in more detail below, the described possible Path of Force Transfer rotating change impulsive force, therefore directing impact power redirects the car door region away from vehicle。In each embodiment, enforement mechanism 302 outside can adhere to steering link 208 (such as via " L " shape connector etc.), is arranged in the end (such as between steering link 208 and gear-box 206) of connecting rod 208 or is incorporated in connecting rod 208。In each embodiment, enforement mechanism 302 can also be positioned at any some place along connecting rod 208。
According to each embodiment, Fig. 3 B shows the wheel torsion system 300 for little overlapping area head-on crash。Normally, enforement mechanism 302 can be scalable design, and includes external shell 310 and internal actuator arm 312, and described internal actuator arm 312 is at least partially situated in the hole of housing 310。In other words, enforement mechanism 302 can be shrinking connecting-rod, and described shrinking connecting-rod is operable to, thus extending actuator arm 312, therefore forces connecting rod 208 to enter tire 110。
In one embodiment, housing 310 can generally cylindrical shape。In other embodiments, housing 310 can be other geometries, for instance but it is not limited to triangle tube, rectangular tube, pentagon pipe etc.。Actuator arm 312 could be attached to piston 308 or merges with piston 308, and described piston 308 is positioned at the inside of housing 310。When enforement mechanism 302 activated, the pressure of the opposing piston 308 in housing 310 can produce driving force F, therefore forces actuator arm 312 to stretch out from housing 310。As it can be seen, in one embodiment, described pressure can produce in pyrotechnics mode。Such as, lighter 304 can light pyrotechnics supplied library 306, therefore produces pressure in housing 310 on piston 308 and drives actuator arm 312 to be displaced outwardly from housing 310。The pyrotechnics of enforement mechanism 302 activates and is well suited for impact applications, because being usually present a small amount of time before impact force passes into wheel to may be used for reaction。
In each embodiment, system 300 includes controller 350, and described controller 350 generally includes via one or more processors 352 of main line 358 communication with one another, one or more memorizer 354 and one or more interface 356。Processor 352 can include but not limited to microprocessor, special IC (ASIC) or be configured to carry out any other circuit of logical operation。Memorizer 354 can store machine instruction, makes processor 352 carry out operation described herein when processor 352 performs described machine instruction。Memorizer 354 can include but not limited to hard disk drive, random access memory (RAM), read only memory (ROM), solid-state storage facilities, removable media (such as CD, DVD etc.) or be operable as any other the permanent computer-readable medium storing the instruction performed by processor 352。
Interface 356 provides the wiredly and/or wirelessly connection between controller 350 and other equipment any amount of in vehicle。Such as, as it can be seen, interface 356 can provide the communication link between controller 350 and any amount of crash sensor 340 in vehicle。According to each embodiment, sensor 340 is positioned on vehicle along Path of Force Transfer, and described Path of Force Transfer corresponds to little overlapping area head-on crash (such as in the 20% of the width of the vehicle relative to vehicular sideview)。Such as, one or more sensors 340 may be located in the crush-zone of vehicle, and described crush-zone generally receives impulsive force in the process of little overlapping area head-on crash。
Controller 350 can determine little overlapping area head-on crash vehicle occur based on the data received from sensor 340。Such as, in some embodiments, controller 350 can be air bag control unit, and described air bag control unit receives the impact data (such as so that it is determined that when the air bag of vehicle should launch) from any amount of impact microphone 340 being arranged in front part of vehicle。If located in a side closest to vehicle those sensors 340 by impact trigger and the sensor 340 more centrally located along the front portion of vehicle is not triggered, then controller 350 may determine that and occurs in that little overlapping area head-on crash。
Determine have been detected by little overlapping area head-on crash time, controller 350 can provide control signal to enforement mechanism 302, causes the actuating of actuator arm 312。Such as, controller 350 via control signal control point firearm 304, can thus result in the actuating of actuator arm 312 and the torsion of wheel。One example of described actuating shows in fig. 3 c。As shown in FIG., the F that makes a concerted effort produced by activating enforement mechanism 302 (such as by flexible enforement mechanism 302) can be transferred to steering link 208, thus results in wheel 110 and rotates around the axis limited by the axle bush 214 being attached to control arm 210。In each embodiment, the direction of rotation of tire 110 so that inwardly rotating closest to the end of wheel impacted towards vehicle, and can rotate (such as producing wheel cabin) further from the end of the wheel impacted away from vehicle。In some cases, when enforement mechanism 302 activated, therefore power F so that steering link 208 departs from the remainder of steering rack is connected (such as depart from steering box 206 etc. and be connected), can maximize the possible rotation amount of tire 110。
Fig. 4 A-Fig. 4 B is the display figure according to the little overlapping area head-on crash on the vehicle 100 being equipped with wheel torsion system 300 of each embodiment。As shown in Figure 4 A, the one or more sensors 340 being arranged in the front end of vehicle 100 can detect the little overlapping area head-on crash with object 112。Such as, 5ms after an impact, instruction can be detected that the sensing data of impact sends to controller 350 by one or more sensors 340。As response, controller 350 may determine that and has been detected by little overlapping area head-on crash and activate enforement mechanism 302。After 20ms, the impact effect on vehicle 100 shows in figure 4b。As shown in FIG., wheel 110 can be forced to reverse by enforement mechanism 302 and make the end farthest away from the wheel 110 impacted reverse out wheel cabin and the vehicle body away from vehicle 100。In this way, wheel 110 does not reoffer the direct Path of Force Transfer between object 112 and the hinge pillar/threshold vehicle of vehicle 100, therefore decreases the fold amount in the car door region of vehicle。
Fig. 5 A-Fig. 5 B is the figure of the vehicle lower side being shown in each embodiment in the process of little overlapping area head-on crash。Fig. 5 A shows the simulation to the little overlapping area head-on crash that the vehicle 100 without wheel torsion system 300 carries out。As it can be seen, passed into threshold vehicle 504 and the body hinge post of vehicle 100 along wheel 110 by the impulsive force of vehicle 100 with the collision generation of object 112, thus result in fold 502。In other words, in common little overlapping area head-on crash, wheel 110 provides the Path of Force Transfer in the car door region making impulsive force entrance vehicle 100。
Fig. 5 B shows the little overlapping area collision of the vehicle 100 being equipped with wheel torsion system 300 according to an embodiment。Be different from Fig. 5 A, detect impact with object 112 time, wheel torsion system 300 can make wheel 110 be pivoted away from threshold vehicle 504。In this way, it is to avoid the fold 502 of display in Fig. 5 A, any collision hence for the passenger accommodation to vehicle 100 protected。
Fig. 6 A-Fig. 6 B is the figure showing the Vehicular occupant room 600 in the process of little overlapping area head-on crash according to each embodiment。Fig. 6 A is corresponding to the impact of display in Fig. 5 A, and wherein vehicle 100 is unkitted and is furnished with wheel torsion system 300。As it can be seen, passenger accommodation 600 is collided in fold 502 especially region 602 around driver's pedal。Therefore, described collision is likely to result in driver's damage, because the structure of passenger accommodation 600 is damaged。As will be appreciated, if impact occurs in the passenger side of vehicle, then it is likely to produce analog result in the passenger side of vehicle。In fig. 6b, it is shown that when vehicle 100 is equipped with wheel torsion system 300 and passenger accommodation 600 during corresponding to impact shown in Fig. 5 B。Especially, by making wheel 110 reverse the car door region away from vehicle, the destruction amount in region 602 is greatly reduced and is likely to protect passenger to avoid damage。
Have been proposed that the various method of testings of assessment vehicle structural behaviour in the process of little overlapping area head-on crash。One described testing standard is issued " little overlapping area front crashworthiness assessment impact test agreement (version II) " by expressway safety insurance association (IIHS) in December, 2012, and wherein in test process, only 25%+/-1% of vehicle width impacts barrier。According to described agreement, measuring thus estimating the intrusion of the passenger accommodation to vehicle along each some place of vehicle in the process of collision。Such as, can steering column, left lower dash panel, brake pedal, parking brake pedal, Vehicular left pedal, pilot set is anchored to two rear seat bolts on floor, left toe dish, above instrumental panel, above and below hinge pillar (such as, for along the total of six point of the hinge pillar of vehicle/A-post) and the some place along the footboard of vehicle carry out the intrusion according to IIHS agreement and measure。Then the intrusion volume at each some place can be assessed, so that it is determined that whether vehicle demonstrates good structural behaviour in the process of test。Such as, the intrusion of 0-15 centimetre (cm) entering passenger accommodation at hinge pillar place, lower section is considered " good ", 15-22.5cm be considered as " acceptable ", 22.5-30cm is considered as " critical ", and 35+cm is considered as " difference "。
Fig. 7 shows that the simulation of the vehicle according to each embodiment is impacted and invades result。As shown in chart 700, baseline vehicle and the same vehicle being equipped with wheel torsion system 300 are drawn to the deflection at each some place in vehicle。As will be appreciated, this analog information wheel torsion system (such as system 300) can greatly reduce deflection on point limiting along all IIHS-of vehicle。Additionally, when vehicle is equipped with wheel torsion system, the maximum intrusion volume entering passenger accommodation in simulation process is also greatly reduced。
Therefore, technique described herein has shown that the structural intergrity of significantly improved vehicle in the process of little overlapping area head-on crash in simulations。Especially, wheel torsion system can force to cause the front-wheel displacement of the vehicle of corresponding impact so that wheel does not reoffer the Path of Force Transfer of the hinge pillar/threshold vehicle entering vehicle。
Although the embodiment of the disclosure is described in detail, the interest field of the disclosure is not limited to the embodiment above, and those skilled in the art use the various changes and improvements forms that the ultimate principle of the disclosure limited in accessory claim book is made to fall within the interest field of the disclosure。
